Title: Improvements in or relating to apparatus for feeding brick moulds to a moulding press for brick making
IPC: B28B7/38
Filed: 1953-03-24
Abstract: 727,098. Moulding bricks. NAAMLOOZE VENNOOTSCHAP MASCHINEFABRIEK VOORHEEN J. ABERSON. March 24, 1953 [March 25, 1952], No. 8085/53. Class 87 (2) Apparatus for feeding moulds to a brick press having a press outlet to one side of its centre, comprises means for feeding empty moulds towards the press outlet in the direction of their width from that side of the press which is opposite to the press outlet in a path under the press, the said path being at a level differing from the level in which the moulds are disposed when being filled through the press outlet, and means at a short distance from the press outlet for displacing the moulds in a vertical direction from the level of the path to the level of filling the moulds, the filled moulds being moved from the press outlet in the same direction in which they are moved in the path under the press. Inverted brick moulds are pushed off one by one from a table 7, in the direction of their width, by a pusher 8, and pass through a sanding machine 9 which sands their insides from below. Each mould is pushed by those behind it across a screen 10, where superfluous sand drops out, and into a device 11 which turns it right way up and which may be so described, for example, in Specification 718,886, this being of a kind which enables an upturned mould to be pushed out of it by the movement of the succeeding moulds. The mould arrives on a table 13, which is raised, e.g. hydraulically, to the level of the press outlet, through which the mould is then pushed by a pusher 14 to the position 5. This is the filling position, and as there are no moulds between it and the pusher 14, i.e. the mould is pushed there directly, the mould is not inaccurately positioned for filling through variation in the widths of intervening moulds and the clay as it fills the mould does not therefore displace the sand from one of the walls. A pressing member 2 is rotated about a shaft 3 with the result that clay fed from a pugmill 1 fills the mould. The filled moulds are pushed across a delivery table 15. A strickling device 16 is associated with the member 2. The movements of the pushing device 8, the inverter 11, the lifting mechanism of the table 13, the pushing device 14, and the pressing member 2 are synchronized and derived from a common drive.

[Also in Division G3] A manually operated spool valve includes a spool 18 movable in opposite directions from the neutral position shown, against a spring 26, to connect inlet 12 selectively with one of two work ports 16, 17, and the other work. port is exhausted through a transfer passage (14), Fig. 2 (not shown), and exhaust port 12. The spool is positively held in each operated position by a ball 32 engaging grooves 22, 24. The ball is loaded by a spring-biased piston 29. When the delivery pressure exceeds a predetermined valve, a pilot relief valve 33 communicating with an inlet transfer passage 13 opens and the pressure lifts the piston 29 from the ball so that the spool is returned automatically to neutral. The piston chamber 31 is drained through a restriction (36), Fig. 2, to a connection 15 which intersects the chamber housing the spring 26. Two or more such valves may be mounted together so that ports 11, 12 and connection 15 in one valve match with ports (41, 42, 43), Fig. 2 (not shown), in another. The relief valve 33 is omitted from all but one of the valves.

Abstract: 492,893. Imitation fires. PREMIER ELECTRIC HEATERS, Ltd., and NEWTON, A. E. March 23, 1937, No. 8470. [Class 126] In an imitation fire comprising a light source and a flicker device for producing moving or changing light beams which produce an appearance of flame or smoke where they impinge on a screen, imitation solid fuel, or other surface, refracting means are provided between the light source and the screen to cause all or substantially all the light images produced on the screen &c. to move upwardly or in another desired direction. The fire shown of similar configuration to that described in Specification 404,302 comprises a recessed metal casing 10 having resistance heating elements arranged above a screen 13 on which the light from an electric lamp bulb 15 is thrown by a rotating spinner 16 formed with irregular openings 18, 19 and bent vanes 17. Translucent or transparent imitation fuel 14 is arranged in the front of the lower part of the casing 10. The spinner 16 is pivoted on a frame 20 carrying the lamp socket 22 and secured to the fire base. A strip 25 secured to the frame 20 carries brackets supporting a rectangular glass sheet 30 and a triangular glass sheet 35, the sheet 30 being plane on its upper surface and formed with inclined arcuate ribs 31 on its lower surface and the sheet 35 being plane on its lower surface and formed with inclined arcuate ribs 36 on its upper surface. The light beams moving approximately parallel to the ribs 31, 36 are unaffected in direction by passage through the plates 30, 35 but the beams moving transversely to the ribs have their direction changed, so that all the images formed on the screen 13 and fuel 14 move upwardly. A piece of " cathedral " glass 34 may be provided above or below the sheet 30 to render the images more irregular and a reflector 37 is arranged below the lamp bulb 15 which is preferably coloured. The spinner 16 may be formed with a glass bearing surface as described in Specification 480,332, [Group XXXIV], and is retained on its pivot by an arm 26 which is secured to the strip 25 and may be adjusted by a screw 27a. Means such as described in Specification 469,934 may be provided for regulating the speed of rotation of the spinner. The screen 13 is preferably provided with a fireclay-coloured adhering skin in which are embedded small glass or other reflecting particles. In a modification the ribs of the glass sheets across which the light beams move have axes of curvature radiating from a centre.

Title: Improvements in and relating to the manufacture of water gas
IPC: C10J3/00
Filed: 1925-03-31
Abstract: 231,866. Humphreys & Glasgow, Ltd., (Assignees of Evans, O. B.). April 3, 1924, date]. Producers.-In the manufacture of water gas, the blast is introduced at an intermediate part of the fuel column and the products are withdrawn from the top and bottom simultaneously. When two producers are used, the products from the first one enter at the top and bottom of the second one and are withdrawn at an intermediate outlet. During the blow, air passes downwards through a superheater a, up a carburettor b, and thence to a producer c wherein it flows upwards and downwards to valves 3 and 4 respectively. After traversing a second producer c', the gases flow to the top of a carburettor b<1> wherein they are burnt by admitting secondary air through a valve 6; if bituminous fuel be used, secondary air may also be admitted at a valve 5 between the producers. The combustion products pass through a superheater a<1> and escape at the stack valve 1. During the run, steam is admitted at a valve 8 and passes through the apparatus in the same direction as the air in the preceding blow; and air may be supplied at a valve 9 to carburet the gas. During the succeeding blow and run, the flow is in the opposite direction.
